Curtiss-Wright Farris - Directional Control Valves

Directional control valves are crucial components in hydraulic and pneumatic systems, providing essential pathways for fluid or gas flow from valve ports to other components. These valves are made up of a mechanically or electrically actuated spool within a cylinder, which can either allow or prevent fluid passage based on its position. The dynamic function of these valves facilitates rapid acceleration and deceleration of fluid flow. Key features to consider when choosing a directional control valve include the number of ports and the available directional positions. These valves are designed for applications that require smooth operation, low-pressure drop, and quick response, making them ideal for use in the agricultural, industrial, and mobile sectors. With a pressure rating of up to 2000 psi and a flow rate capacity of up to 10 GPM, they are built to deliver precise fluid control. There are various types of operating mechanisms for these valves including hydraulically operated for higher precision, manually operated with levers or paddles, and mechanically operated which are subject to wear due to the use of cams, wheels, and rollers.
